[Meta Releases Muse Spark 1.3 Model, Advancing Personal AI Agent Development] According to Gelonghui, Meta released the Muse Spark 1.3 model update on Wednesday, stating that this version has significantly improved performance in coding and intelligent agent tasks. Meta AI head Alexandr Wang said the new model is "on par with cutting-edge models" and will pave the way for future personal AI agent products, helping users achieve AI assistants capable of working on their behalf around the clock. The price of Muse Spark 1.3 remains consistent with the previous version, and Wang described this pricing strategy as "aggressive." Meta also noted that its "Contributor Tier" option has been well-received by developers. This program significantly reduces the cost of coding products by allowing Meta to use developers' work to improve the model. Currently, a "meaningful double-digit percentage" of developers have opted into this program.
